Question

1. 54.25 in. x 2.54 mm/cm
2. (9.8547 x 10^6 cm) (10 mm/cm) (1 m/ 1000mm)

Answer 1

There is a mistake in the first question in the way it is written:

1).

If you are trying to convert in ---> cm:

54.25in x (2.54cm/1in) = 137.8cm


But if you are trying to convert in --> cm --> mm:

54.25in x (2.54cm/1in) x (10mm/1cm) = 1378mm



2).

9.8547x10^6cm x (10mm/1cm) x (1m/1000mm) = 98547m

Simplified:

9.8547x10^6cm x (1m/100cm) = 98547m
